What is the difference between channel error or distortion and eavesdropping?

• staunton 1y ago
  For eavesdropping, there is someone there who cares about what you're sending and is successfully learning things about it.

    How can one quantumly differentiate between photon lost due to eavesdropping and photon lost due to some other error?

      Other than by going around and finding the eavesdropper sitting somewhere, one cannot.
